  • "I think the chances are very high FDA to approve it," Bourla told CNBC, saying he believes the agency will be pleased with the data.

  • Pfizer and BioNTech asked the FDA last week to expand the authorization for its vaccine to most kids under 5.

Pfizer CEO Albert Bourla on Tuesday said he believes the Food and Drug Administration will authorize the company's Covid vaccine for children under 5 years old under a fast-track process that allows the agency to review the data as soon as researchers compile it in real time.

"I think the chances are very high for FDA to approve it," Bourla told CNBC's Meg Tirrell, while noting that the regulatory process still has to play out. "I think that they will be pleased with the data and they will approve," he said.
